Factorisation theorems for generalised power series [PDF]
, 2017 Fields of generalised power series (or Hahn fields), with coefficients in a field and exponents in a divisible ordered abelian group, are a fundamental tool in the study of valued and ordered fields and asymptotic expansions.

Proceedings of the American Mathematical Society, 1960 Then G is a rationalfunction of x if and only if a is a rational number. As usual, [x] denotes the integral part of x and { x } the fractional part of x, so that x = [x] + { x }. We first prove LEMMA 1. Let a be a real irrational number, and let R be a finite set of non-integral real numbers. Then there are infinitely many positive integers m such that

Natural Frequencies of Axisymmetric Vibrations of Thin Hyperbolic Circular Plates with Clamped Edges
International Journal of Applied Mechanics and Engineering, 2017 A free vibration analysis of homogeneous and isotropic circular thin plates with nonlinear thickness variation and clamped edges is considered. The limited independent solutions of differential Euler equation were expanded in the power series based on ...

STATCOM Model Using Holomorphic Embedding
IEEE Access, 2019 Convergence characteristics of existing Newton-Raphson (N-R) load-flow based FACTS devices models are affected by the choice of initial conditions. Many a time, a solution is either spurious or fails to converge.

Mathematics, 2021 In this paper, we deal with some applications of the network simulation method (NMS) to the non-linear differential equations derived of a parametric family associated to stated problems by Newton in and others like the parabolic mirror and van der Pol ...

Irrational Power Series. III [PDF]
Proceedings of the American Mathematical Society, 1965 Several writers (see [1 ] for references) have shown that if f(y) satisfies various conditions, then F(x) is not a rational function of x, and some have shown that the circle x| = 1 is a line of essential singularities for F(x). I notice a very simple way of dealing with such questions. The method is really that of Hecke, but its possibilities have not
